Abstract
We consider the process of high-order harmonics generation (HHG) in the xenon atom enhanced by the
intershell correlation between the valence 5p and inner 4d shells. We derive the HHG spectrum from a numerical
solution of the one-electron time-dependent Schrödinger equation multiplied by the enhancement factor taken as
the photoionization cross-sections ratio calculated with and without the intershell correlation. Such a simplified
approach is adequate to describe the experimental HHG spectrum reported by Shiner et al. [Nat. Phys. 7, 464
(2011)] generated by a single color IR laser. Similarly, we find good agreement when applied to the two-color
driven HHG spectra reported by Faccialá et al. [Phys. Rev. Lett. 117, 093902 (2016)].
